VAPORIZER FOR EXPLOSlVE-ENGINES.

SPEGIFICATION forming part of Letters Patent No. 682,905, datedSeptember 1*?, 1901. Application tiled May 20, 1901- Serial No. 61,047.(No model.)

To a/ZZ whom t petty concer-n:

Be it known that I, JOHN C. BLAND, Jr., a citizen of the United States,residing at Sewickley, in the county of Allegheny and StateofPennsylvania, have invented certain new and useful Improvements inVaporizers, of which the following is a specification, reference beinghad therein to the accompanying drawings, forming part of thisspecification, in which f Figure 1 is a central vertical sectional viewthrough my improved vaporizer. Fig. 2 is a horizont-al sectional view onthe line II Il of Fig. 1. Fig. 3 is a sectional view on the line III IIIof Fig. 1. Fig. 4 is a similar sectional view on the line IV IV ofFig. 1. Figs. 5 and 6 are views similar to Fig. 1, but illustratingmodified constructions.

My invention relates to devices for Vaporizing hydrocarbon and otherliquid fuels; and

it consists in means for disintegrating and com mingling the liquidfluid with proper proportions of air in order to deliver the mixture toan explosive motor or other consuming device, and the invention relatesto means for such purposes and also to means for regulating andcontrolling the supply of fluid and air, respectively.

Referring to the drawings, 2 represents the case, with which isincorporated the other elements of the invention, the case having at itsupper portion an attached liquid-fluid-supply connection 3,0pening intothe chamber 4, containing the needle-valve 5, by which the sup-l ply ofiiuid may be accurately controlled. InV

the construction shown in Fig. 1 the seat- 6 for the valve is formed inthe upper portion of a downward-extending hollow stem 7, whichterminates in a conical hood 8, which hoodis surroundedbyadownWardly-extended shell 9, formed integrally with or attached tothe top 10 of the case. The case and likewise the shell are preferablycircular in cross-section, and between the shell 9, which extends onlypartially into the interior of the case 2 and the sides of the case 2,is an intervening space 11, into which the commingled iuid and air willrise after emerging from the lower end of the point of which extendsupwardly to the lower end of the hollow stem 7, and which is adaptedtoreceive the downward-dropping fluid,

which will spread out over the cone 12 in a thin covering of liquid uponthe outer surface of the cone, from the lower edge of which it will dropupon the sides of a downwardly-extended dome 13, of fine wire-gauze,which projects downwardly to within the interior of the lower portion ofthe shell 2. The gauze may, however, be of other form or construction,as will be readily understood. The cone 12, hood 8, shell 9, and dome 13are secured together in any suitable manner at the lower edge of theshell, so that their relation to each other ywill remain fixed, and asthus constructed it will be seen that there is provided between theinner surface of the cone' a narrow coniform space 14, so that thedownwardly-dropping fluid may either flow upon the upper surface of thecone or upon the inner surface of the hood and in either case will bedelivered at the lower peripheral eX- tremity of the shell 9, fromwhence it will fall into and upon the inner sides of the wiregauzedome13. gauze covering dome-shaped it will be understood that any other formmay be utilized which will give good results. Through the lower portionof the walls of the hood and of the cone are providedperforating-openings 15 16, preferably in register with each other, andin the upper portion of the top 10, Within the peripheryA of shell 9,are provided one or more air-inlet openings 17, through which air mayenter, and such air will pass through openings 15 and 16 to the interiorof dome 13, and in such action will take up or absorb a certain' portionof the liquid iluid, which as thus charged or' suspended in the air willbe carried by it into the interior ot' the case 2 and from thenceoutwardly to the deliveryopening 18 to the motor or other point of-`consumption. For the purpose of more thoroughly commingling the air andfluid, eitherl or both openings 15 16 may be covered by In place ofmaking the wirey thin gauze 19, as indicated, and it will be understoodthat these openings as well as their size may be regulated and adaptedto the particular purposes in view.

Through the upper portion of the case 2 extends one or more perforatedopenings 2O for the purpose of admitting a diluting current of lair; Forthe purpose of accurately regulating ICO such supply any suitablecut-olf mechanism may be used, as a ring 21, provided with correspondingopenings 22, which ring may be rotatably mounted upon the case, so thatthe supply of air may be accurately controlled or entirely shut o, asmay be desired. At its lower portion the case 2 is provided with adrain-cock 23, by which any excess of fluid not taken up by the air maybe drained away, and it will be observed that by the location of theoutlet-opening 18 at the upper portion of the case the device as soarranged provides for the collection of any excessor unabsorbed liquid,and likewise insures the regularity of the mixture-supply to the motor.

In the construction shown in Fig. 5 the hood Sis dispensed with, thevalve-seat 6 being merely screwed up into the top 10 and valve-case 4,while a cone 12 is alone mounted in the interior of the shell 9 and isadapted to receive the downward-dropping liquid and to spread it out ina thin film and to discharge it upon the interior of the gauze dome 13.

The `,frauze-covered openings 16 are also provided, and the case is inevery respect the same, the operation of the absorption by the incomingair and the circulation of the miX- v ture being substantially the sameas already described. Ihave, however, provided ashort tube 7 to insurethe accurate dropping of the liquid upon the point of' the cone.

In the construction shown in Fig. 6 the cone 12 is dispensed with andthe hood 8 retained,

the liquid in such case dropping downwardlyl upon the interior walls ofthe hood, spreading out thereon in a thin film, and being dischargedupon the inner side of the gauze dome. The openings 15 may likewise becovered with gauze, as shown, a-nd the construction of the deviceotherwise as well as its operation, the circulation of the incoming andoutgoing currents of air and mixture being the same as I have alreadydescribed.

I am aware that perforated cones have been employed in devices for thegeneral purpose of vaporizing liquid uids, and am familiar with thepatent issued to B. W. Grist, No.

545,125, but believe I am the first to make a vaporizer in the mannershown and described.

The advantages of my invention will be readily appreciated by thosefamiliar with the use of fluid motors or those utilizing liq" nid fluidin any case where it is desirable to finely commingle and charge thesame in an air-supply. It is very simple in construction,

economical, and not liable to get out of orshown, but to include allsuch changes and i variations within the scope of the following claims.
